Patent FR-2525053-A1 (FR)
Title: Fault detector switch for transmission access selector - comprises bistables with gate and inverter circuit which control switching of couplers
Inventor: NICOLAS JEAN-YVES
IPC: H04L1/22
Filed: 1982-04-09
Abstract: A transmission channel (1) has modems (11,12) and each end and operates in duplex mode. Access in the respective direction is made via couplers (5,6) which are connected to interfaces (7,8). One interface (8) contains decision circuits comprising two JK bistables whose Q outputs are applied to an exclusive OR gate (14). Input signals (OB1,2) from a fault detector are applied through the interfaces to the bistable clock inputs and by feeding back the gate output (X) and its inverse to the JK inputs a valid or invalid command signal is issued. This command signal controls operation of one of the couplers to allow transmission of signals through one or other of the interfaces (3,4).

Patent FR-2530376-A1 (FR)
Title: Thermostat
IPC: H01H37/54
Filed: 1982-07-16
Abstract: The instrument 10 is intended for monitoring temperature. There are known instruments of this type which, as well as an active fast-response bimetallic disc, have a fast-response elastic disc which produces the actual contact pressure in the closed position. In order to carry out an operation, the fast-response bimetallic disc has to overcome the whole of the force from the fast-response elastic disc producing the supporting pressure. To create the desired force, the bimetallic disc must be quite large, otherwise the supporting forces are so small that the conductivity and performance during operations are relatively poor. The invention achieves its aim by using two stamped-out fast-response elastic discs 22, 24 and mounting them in opposition. This method makes it possible, with small fast-response bimetallic discs 26, to obtain contact pressures ensuring that the instrument 10 is highly reliable.
Patent FR-2531520-A1 (FR)
Title: Orientable solar collector.
IPC: F24S50/20
Filed: 1982-08-04
Abstract: The invention relates to a solar-energy collector and a method of orientation thereof and more particularly a collector which can be oriented relative to the direction of the sun's rays without making use of electrical elements. According to the invention, the collector comprises two series of heat-sensitive capsules 5, 6 filled with a volatile liquid and connected respectively to expandable chambers 9, 10. These two series of heat-sensitive capsules 5, 6 are fixed respectively on either side of the receiving surface 1 and are slightly tilted in a symmetrical fashion with respect to the latter. Two expandable chambers 9, 10 are connected to them and thus define a force which can be used to orient the collector by virtue of the difference of the internal pressures within the capsules 5, 6. The invention can be adapted advantageously to the pumping and distillation of water, and to heating water for domestic or industrial purposes.

The gables are produced in the same manner but by means of trapezoidal frames. The roof consists of frames 5 formed by two sections 6, a ridge beam 8 and a section 7. The structure is assembled by bolts 9.
Patent FR-2537455-A1 (FR)
Title: Catalysts based on iron, chromium, potassium and at least one rare-earth metal, their preparation and their use in dehydrogenation reactions
Inventor: COURTY PHILIPPE
IPC: C07C5/333
Filed: 1982-12-14
Abstract: Catalysts are described which contain iron, chromium, kaliophilite of formula Al2O3.2SiO2.K2O and potassium in excess in relation to that present in the kaliophilite, as well as at least one rare-earth metal or a rare-earth metal compound in a proportion, calculated as oxide, of 1 to 15 % by weight relative to the weight of the finished catalyst. The presence in the catalyst of a rare-earth metal oxide optionally at least partially precombined in the form of a mixed oxide, of perovskite or spinel type, with Fe, Cr, Co, Ni, Al or V, endows the catalyst with an improved activity and/or selectivity in dehydrogenation reactions of hydrocarbons, in particular of ethylbenzene to styrene.
Patent FR-2542607-A1 (FR)
Title: Autostatic module for abduction of the lower limbs
IPC: A61F5/01
Filed: 1983-01-14
Abstract: The invention relates to a method for cutting out from a material with elastic properties which makes it possible to hold the hips of a child in abduction in order to prevent any risk of dysplasia. The device resulting from the method consists of a monoblock module of dense foam into which the child is placed in the correct position, by virtue of the deformable nature of the material (Figure 1); the elastic return of the fastening element against the holding element being obtained by an incomplete cut-out 15 from the frontal plane of the module. This autostatic nature removes the requirement for any other external fastening means for the module and guarantees the symmetry of positioning of the coxofemorals as well as the constant harmlessness of the pressure stresses exerted at this level however many times the module is put on and taken off. Holding of the trunk and of the pelvis in the frontal plane by lateral stops 10 eliminates the risk of forming a height-related obliquely contracted pelvis. The size of this module is dependent on two dimensions: the seated height of the child 15 and the interpopliteal distance. Covering the module with a fabric may improve its appearance.

Title: Injection moulding needle valve
IPC: B29C41/00
Filed: 1983-12-08
Abstract: Needle valve has the leading end of the needle guided by a precentring sleeve which has at least one (three lobe-shaped) channel for the passage of the melt during the centring procedure. This sleeve has a female cone with a taper angle which is smaller than the angle between the lines from the forward end of the needle to the rear end of a conical transition of the needle. The precentring sleeve  has a female cone  and on it three lobe-shaped extensions . The valve needle has at the forward end a cylindrical sealing area (6) of reduced dia.. The taper angle of the cone is smaller than the angle between the lines joining the edges of the forward needle end to the transition end . The dotted lines indicate how a deflected needle is protected. This ensures that needle deflections cause no damage to the forward end of the needle and that no melt has to be deflected into cold areas.
